This is what I receive from every video that I am trying to play on YouTube:
I do not understand what is happening. All videos from other websites are working fine.
What is this HTML5 player and how can I completely remove it from my computer?
I am using Windows 7.

It is most likely an issue specific to your graphics card. Please file a bug at https://bugzilla.mozilla.org/enter_bug.cgi?product=Core then choose the video/audio component. Paste in the information from about:support and the right people will get notified and will jump onto it immediately.
